I just threw away seven 2200 last year. I got fed up with keeping them around, telling myself I was going to finally un clog them all.
Drain the inks out and flush the system with isoprol alcohol?
I wouldn't leave them in, that's for sure._________________r.c. durston

You have put it back in the printer at some point in the future. Under certain circumstances the printer may tell you that a cartridge is empty when in reality it is not, or a printer may tell you a cartridge still has ink in it when it is really empty, and this all depends on how you removed the cartridge just before installing this one.
